The hottest trend of packaging machinery design 1

Trends in packaging machinery design (1)

German packaging machinery design strives to serve customers, especially large enterprises, based on Market Research and market analysis. With the development of science and technology and the intensification of market competition, customers have higher and higher requirements for mechanical performance, mainly in the following aspects:

1. High productivity to meet the requirements of delivery time and reduce the needs of process circulation costs; For some products, packaging machinery and production machinery are also required to be connected

2. To meet the needs of product renewal, packaging machinery should have high flexibility and flexibility

3. There are few equipment faults, and remote diagnosis service can be carried out in case of faults

4. Less environmental pollution, including noise, dust and waste pollution

5. The investment in purchasing equipment should be as little as possible, and the price should be as low as possible

German packaging machinery manufacturers and design departments have taken the following measures to meet the above customer requirements:

first, improve the automation of process flow

a few years ago, automation technology accounted for only 30% of packaging machinery design, and now it accounts for more than 50%. Microcomputer Design and electromechanical integration control are widely used. The purpose of improving the automation of packaging machinery is to improve productivity; Second, to improve the flexibility and flexibility of the equipment; Third, in order to improve the ability of the packaging machinery to complete complex actions, that is, the manipulator is used to complete the packaging process. For example, the packaging of chocolate candy has realized the replacement of the original manual with a manipulator

the automatic design of packaging machinery has the following two main characteristics and one key printing experimental report points:

1. Each manipulator is controlled by a separate computer

in order to complete complex packaging actions during "1035" of a packaging machine, it needs to be completed by multiple manipulators. When completing the packaging action, under the information recorded and monitored by the computer-controlled camera, the manipulator completes the specified action according to the instructions of the computer program to ensure the quality of the packaging

2. It has high resolution of material and thickness

in the process of packaging, the thickness and material changes of packaging materials are not easy to be recognized by human eyes, so computer-controlled cameras and detectors are often used in the design of packaging machinery to distinguish the thickness and material changes of packaging materials. The camera has been developed to be able to check and distinguish the captured pictures by itself and display them on the display screen. At present, the rotating speed of the machine cannot be changed during processing. In the future, the rotating speed should be changed according to the change of materials after differentiation, so as to control the work under the optimal state, complete the packaging process in the shortest time, and realize automatic cleaning, automatic disinfection and automatic cleaning

second, improve productivity, reduce process costs, and meet production requirements to the greatest extent

German packaging machinery, especially beverage, beer filling machinery and food packaging machinery, has the characteristics of high speed, complete set, high degree of automation and good reliability. Its beverage filling speed is as high as 1200 bottles/hour, and cigarette packaging is 12000 pieces/minute. Increasing the speed of the machine is a complex problem. The faster the speed is, the lower the production cost of a single piece is, but the use area of the plant will increase

in addition, the motor speed is also limited, so you can't go as fast as you want. Generally speaking, increasing the speed by% will bring a series of complex problems

to improve productivity, in addition to increasing the speed, we can also try to solve it through other channels:

1. Adopt continuous work or multi head work mode

the working mode of packaging machinery has intermittent and continuous mode. When designing, we should strive to design continuous work, which will improve the production rate; There can also be multiple production lines in one equipment to produce the same product or several different products, but the reliability must be improved

2. Reduce the scrap rate and provide a fault analysis system

waste products cause huge losses to production, not only product losses, but also material losses. Therefore, we should try our best to reduce the scrap rate; When selling packaging machinery, it should also provide fault analysis system for maintenance services, that is, modal analysis to find faults, or remote diagnosis through inter, so as to meet the needs of customers to the greatest extent. In the future, the packaging machinery should be further intelligent, that is, the equipment should find and solve the faults by itself, so as to reduce the scrap rate and failure rate and improve the normal productivity

3. Integrate product production machinery and packaging machinery

many products are packaged after production, which is also conducive to the metal tensile test. It is the most common one that can improve the productivity of products according to national norms. For example, the chocolate production equipment and packaging equipment produced in Germany are controlled by a system. The key to the integration of the two is to solve the problem of matching each other in productivity. Packaging machinery often becomes the bottleneck of production, so it is necessary to provide equipment with different productivity. (to be continued)
